5.1
Venting the appliance
·
Open the water intake.
·
Allow the appliance to run without the high-
pressure hose until the water emerges without
bubbles.
·
Then connect the high-pressure hose.
·
If the spray lance and high-pressure nozzle
have already been fitted to the high-pressure
hose, you can vent the appliance as follows:
With the hand-held spray gun open, switch
the appliance on and off several times at
intervals of 10 seconds until the water emerges
from the high-pressure hose without bubbles.
5.2
High-pressure nozzle
·
The effectiveness of the high-pressure jet
depends to a great extent on the spray angle.
A 25° fan jet nozzle is usually employed
(included in standard delivery).
·
Other nozzles are available as accessories.
0° full jet nozzle
for stubborn dirt.
40° fan jet nozzle
for sensitive surfaces.
Dirt blaster
for thick layers of dirt.
Variable angle nozzle
with adjustable spray angle
·
At first always direct the high-pressure jet
from a greater distance at the object which is
to be cleaned, thereby preventing damage
from excessive pressure.

Adjusting the operating pressure
and flow rate
·
You can adjust the operating pressure and
flow rate:

the pump head
– Screwing in the adjusting screw increases
the flow rate and operating pressure
– Screwing out the adjusting screw
decreases the flow rate and operating
pressure.

– Turning the control sleeve to the left
decreases the operating pressure and
water volume.
